fix dim test
fix dim test again
added the 'dim-test_for_rings_over_integers.tst' to 'Short.lst', also now the test file ends with a '$'

improved genus documentation for 1-dim affine variety input
Merge pull request #380 from surface-smoothers/addDimTestForRingsOverIntegers

Add dim test for rings over integers
fix: comment splitting via hnexpansion (deg problem)
chg: doc. of genus: requirement for coeffcients
add: default attrib for rings" "ring_cf": rField_is_Ring
chg: ASSUME prints current ASSUME- source line (up to 79 chars)
fix: rAssure_SyzComp: ringorder_c is sufficient
add; rHas_c_Ordering
fix: do not use regularity with rField_is_Ring in idSyzygies
fix: cond for regularity (idSyzygies)
fix: map alg/trans. extensions: undefined memory
fix: kronecker multiplication over Fq
fix: bug in modular multiplication over Q(a)
chg: more tests for factorization
